Help!!!!!!!
 

Hay all I have a 79 celica supra and I cant get the thing to charge I replaced the alt. 3 times and I put a new Interstate batt, in it. I have power to the alt. on the 2 small wires I also found a relay thats called a (charge lamp relay) I dont know enough about it to know if it could be the prob. or not and its kinda expensive to just try and new Ideas would be great or if anyone knows about that relay.

Is it not charging or is the battery draining when allowed to sit? Yes, the charge circuit definitely could be to blame.
